It could be a lot of different things as far as the heated seat goes. Could be a bad switch, disconnected wire and/or bad unit.
If you hear a low hum that is steady, then it is caused by interference. Did the previous owner did any modifications to it? You might want to look around or take out the rear seat to see if the stock amplifier wirings are all spliced up or not.
